To all 'whom t mayconcern.'

Be it known that I, Frank` L. MEHRING, a citizen of the United States, and a resident of Charlottesville, ini the county of. Albemarle and State of Virginia, have invented a new and useful lmprovement in Barrell-lead Presses, of which the following is a specification.

My invention relates to improvements in barrel head1 presses, and it consists in the constructions, combinations and arrangements-'hereindescribed and claimed.

An object of my invention is to provide a barrel head press, including as one of its essential features, the novel construction of follower with the resilient follower arms, and the ballbearing on the screw shaft.

Another object of the invention resides in theV manner of mounting' the follower and the ball bearing disks, on the screw shaft.

f Other objects and advantageswill appear in the following specification, 'reference being had to the accompanying drawing, in which j 1 1 Figure l is a side elevation showing the device applied to a barrel, a portion of the barrel being shown in section.

Fig. 2 is an enlarged sectional view,l

Fig. 3 is a cross section on the line 3 3 of Fig 1, and

Fig. l is a detail view showing the engaging members on the resilient follower arms and the bottom disk.

In carrying out my invention, I provide a bridge 1 which has a bushing 2 in the center, and is secured in position by the bolts or rivets 3 which also include the binding` plate d on the upper surface of the bridge 1. Spring arms 5 are attached to the ends of the bridge 1, and have additional support in the braces 6, the means for securing the arms and the braces to the bridge, being arranged substantially as shown. The spring arms 5 terminate in hooks 7 on the bottom, for engaging the lower chine of the barrel 8.

A screw shaft 9 occupies the threaded bore of the bushing 2, and has a headlO atthe to o, through which a handle 11 is thrust. 'l e screw shaft 9 has a smooth shank 12 nearY the lower end. A threaded enlargement 13 is located between the shank 12 and Y Specification of Letters Patent.

portion of the shank 12.

rlhe bottom disk 18 andthe resilient fol lower arms 20 are additionally bound to- The bottom disk 18 has f smooth bore which is occupied by the smooth gether by a featherv and groovey connection.` c

The resilient arms-2O are preferably stamped or cast fromV one piece. inthe shape of` a cross, thus providing alcentralsolidportion 23 on 'which the feathers 24: are formed.

These feathers fit into grooves 25 on the lower surface of the disk 18. Relative turn-f ing of the disk 18 on the follower arms is prevented by this connection.

The free endsv of the follower arms 2O are bound together byl a. follower ring 26, which is adapted to engage the head of the barrel,

when the head is to beppressed into position as shown in the drawing.

The operation of the device is as follows: The spring arms 5 are irst hooked overthe lower chine ofthe barrel, and the follower occupies the normally elevated position so that the head of the barrel may be readily placed in position on the contents of the barrel. The follower is then screwed down until the ring 26 meets the head. Continued turning of the screw shaft 9, presses the head down until it springs in place in the annular groove near the upper edge of the barrel.

There is an advantage in making the follower arms 20 resilient, to a certain degree. The degree of resiliency will of course be greater when the follower arm piece is stamped from a sheet of metal. The follow er arms will possess a lesser degree of resiliency, when the piece is cast. ln any event, there is a certain degree of resiliency in the arms 20, and this resiliency permits the follower ring 26 to conform to any inequalities in the head 27. For instance, the head 27 may not be perfectly horizontal, but may slant at such an angle that were the 'mounting 0fthe followerfing rigid, only one point on the head Would be pressed upon, and so the proper seating of the head in the groove would become uncertain.

This explanationgof course leads to the understanding of the value of resilient armsV which, as pointed out above, cause'the fol-V lower ring to adjust itself to unequal positions of the head and yet permit the free turning ofthe top ball bearing disk. The provision of the ball bearing Ybetween the screw shaft and the follower, is novel in devices of this kind. Obviously, the device may be operated withv less effort than formerly, andconsequently in less time.

I claim:

l. In a barrel head press, a screw shaft, a bearii'ig including top and bottom disks carried by the screw shaft, a follower comprising a cross-shaped piece including a solid mid. portion secured to the bottom disk and resilient'arms radiating from the mid pory v tion, and a follower ring embracing the free A copies of this patent maybe obtained fior ends of the arms.
